Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
New build mastic for homes and businesses in Warren Street
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, kitchens and show homes, and people most often call us about joints pulling apart as timber shrinks and skirting joints opening in the first winter.
In a village or hamlet like Warren Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
A one-year guarantee comes as standard.

What we are called out for in Warren Street
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
It’s worth asking for a quote if you see:
- Sealant work across a run of new homes
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
- Cracked sealant around new window and door frames
For new homes near Lenham station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Surfaces we seal

- Windows & doors

What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Warren Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.

How long does new build mastic take?
A typical job takes anything from a few hours to several days, depending on the number of plots. We will confirm how long when we quote.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
